 Bootstrap time on cygwin for 3.2 with java increased by factor of 2-3 
 about the time this patch went in. All the increase seems to be in
 libjava.

 I don't have accurate times, but it used to bootstrap and test overnight
 on a 1.5 GHz P4, and now it takes around 24 hours. 

Mark does your patch result in more file manipulations?
That is usually the killer that only shows up clearly on
non-Linux systems.
